formal complaint for gross negligence, warranty breach, and repeated mechanical failures involving my RAM 2020 ProMaster 1500 HR (VIN: [XXX] ). The vehicle remained out of service for 1 year, 4 months, and 18 days due to transmission damage. Five days after the final delivery, the transmission failed again. in addition, there is a persistent problem with the steering system. The dealership insist that this is the " Normal Operation ", but this is a defect according to the owner’s manual. The transmission is covered by the manufacturer’s warranty, and the supposedly replaced parts are covered by the GWC Warranty. November 14, 2025, the vehicle was transported to Miami Lakes Chrysler Jeep Dodge RAM to be inspected by Mr. Christopher Byrne (Bosch EAA, [XXX] ), the technical inspector assigned by Stellantis to conduct the evaluation. After returning home with the vehicle following this inspection, new oil leaks became evident, apparently originating from the engine. It has now been one month and ten days since my initial communication with Stellantis FCA, and I have not received a single official update regarding the status of my claim. Likewise, ten business days have passed since the inspection performed by Mr. Byrne, without any delivery of the diagnostic results, findings, or a corrective action plan. I appreciate your attention to this matter and expect it to be handled with the urgency and rigor required for a case involving mechanical safety risks and manufacturer responsibility. I look forward to your prompt response. Finally we have not received an effective response, and the vehicle remains inoperable at my residence.

I, [XXX] , hereby declare under oath that I have been a victim of fraud, negligence, and unfair business practices by Ford of Kendall. On [XXX], I purchased a 2020 RAM ProMaster 1500 HR (VIN: [XXX] ) for $45,906, based on the seller’s claim that it was inspected, certified, with a clean title and under manufacturer warranty, and eligible for an extended warranty.” A CarMax report dated September 28, 2025, later revealed that the vehicle had been involved in a severe prior accident that was never disclosed, valuing it at only $5,500 and causing a loss of over $40,000. Since purchase, the vehicle has only been operational for about four months, spending the rest of the time in repair shops due to serious and recurring mechanical failures, including leaks, oil contamination, and defects in the steering, transmission systems and other problems. Check Google reviews by [XXX]. The alleged “repairs” were superficial, mechanical failures persisted, and invoices, service receipts, and technical reports were omitted, demonstrating a total lack of transparency. The vehicle represents a road safety risk and direct economic loss. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am writing to formally file a complaint for gross negligence, excessive delays, and repeated mechanical failures regarding my RAM 2020 ProMaster1500 HR; VIN: [XXX] at the authorized dealership Bomnin-Doral in Miami, FL. The vehicle remained at the dealership for 1 year, 4 months, and 18 days due to transmission damage and other mechanical issues. Five days after final delivery, the transmission failed again. Despite multiple attempts to communicate, no effective response has been received, and the vehicle remains inoperable at my residence. A steering issue also persists: when turning the wheel fully to the left or right, it does not return to its original position and must be manually assisted, posing a serious accident risk, especially in turns under 90° or U-turns. The dealership claims this is “NORMAL,” which we strongly dispute. The transmission is covered by the manufacturer’s warranty, and other damaged parts by the GWC (POWERTRAIN PLUS) warranty. These problems have caused significant financial losses to my business, family, and me personally, as well as severe impacts on our health and emotional well-being. Personally, the stress and frustration led me to the Emergency Room at Jackson West Hospital, where I was diagnosed with an ischemic stroke (Right MCA Stroke) and later surgically treated at Jackson Memorial Hospital. To date, no one has contacted us or provided an effective solution, which constitutes gross negligence and a flagrant violation of my consumer rights. I request that this case be reviewed immediately, and a fair investigation be opened so that actions like this do not go unpunished. I also request full financial compensation for all damages, including emotional and moral distress, punitive damages, and a full refund of the vehicle. I have videos and other photos that I can send but it doesn't like me send it because the videos and photos are too big in storage, but I can send it via email. Sincerely and at your disposal INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO

The vehicle fails to go into gear when placed in DRIVE until the accelerator is pressed. It then shifts extremely hard into first gear and continues to shift with a hard thump into sequent gears until it reaches the higher gears. Extremely dangerous in city traffic. I managed to get the vehicle to a dealership for a warranty repair. They diagnosed the problem as a defective transmission. After five months of waiting, a new transmission was received and replaced. However, it didn't fix the problem. The dealership's fix was to order a second transmission. I'm still waiting with no ETA after eight months.

The transaxle downshifts whenever the accelerator pedal is released and the vehicle gains speed. This happens anytime, not when the driver wants to slow down. In the snow this has caused me to loose traction (unwanted engine breaking). There is no way to turn this off. I've spoken with other ProMaster owners and they all report the same issue. The transaxle should only offer engine breaking if the driver is depressing the brake pedal. Not whenever the vehicle accelerates. I believe this feature should only be active in "tow/haul" mode, and not be active in "Drive" mode. Even when the gear selector is in "manual mode" the unwanted downshifting still occurs. This has caused me to loose control (steering) as the vehicle is FWD on several occasions. No other vehicle I've ever driven acts this way. This has caused me to go off the road in snowy conditions.
